IMO. Ppl are saying Mage due to frost pvp. PVE the honor still goes to paladins. Protection is #1 in both survivability and threat, while still being by far the easiest tank to play. And yes I have one of each. Holy still tops meters, has the beat cooldowns etc. Don't raid with a ret so can't speak to that. This is all based on personal experience of course.

I hate healing paladins in heroics...they always seem to take tons of damage compared to warriors, druids and even dks....

Mages, they are the class with the most control in a pvp scenario where everything is about control... And they got mad dmg... a skilled mage can seriously solo 2k in 2v2 if a bit lucky.
I would also say hunters are up there, honorable mention to DKs and resto shamans as well...

To be fair the people who honestly believe that blizzard favors a single class are stupid plain and simple. That doesn't make any logical sense, why on earth would a company make one section of it's player base better than the rest?

Why? I dunno, why would they nerf any other classes into being one of the worst? Same reasons I'd guess...

to everyone thats saying mage ,could you please explain other then just saying mage. i play a mage and my dps is on par with mm and surv hunters, unholy dk's and warriors if we all are around the same gear. look at the website state of dps and we are like 7 down on the list. so instead of saying mages are op could you explain what makes them op. cause i sure would like to get in on it.

Ok what are ppl thinking voting druid, resto is good yes, but no more then they were in wrath if you were doing it right. Feral got the nerf bat square between the eyes afte the ensidia shenanagins. Bommkins have been nothing but nerfed since the pre cata patch in wrath with the eclipse changes, yes were usually topish on the meters but their trying to change that as fast as they can. So yeah id vote druid too....

Mages are oped, end of story. Frost DK's def need something changed, and are in a close 2nd. Personally I liked the old rune system for frost, and wish it would go back to 4.0.6 status, where it was fun to play.

No, that had nothing to do with it. They nerfed bleeds because they were too powerful in PvP. The Shred buff that came in the same patch effectively made the end damage difference negligible anyway. The only real nerf to kitties so far has been the shapeshifting nerf.
